The formulas and the directions of the forces acted on the ends of the fault in earthquake source located in the tension region distributed radially have been derived theoretically.
从理论上计算了位于径向分布的张力区中孕震断层端部所受力的表达式和方向。
The NNE fault system is mainly controlled by tension-torsional stress, and the NNE-NE fault system by these factors: boundary condition, sedimentary facies zone and regional tensional stress.
NNE向断裂系统主要受张扭应力作用控制；而nne - NE向断裂系统主要受边界条件、沉积相带、区域张应力的控制。
